Publication number: 20240058732Abstract: An annular water removal system (AWRS) for an air cycle environmental control system (ECS) includes a line replaceable unit (LRU) configured to output air flow, and a water collector coupled to the LRU. The water collector includes an upper portion and a lower portion. The upper portion includes a coalescing unit having a collector inlet to receive the air flow and configured to coalesce moisture from the air flow output from the LRU. The lower portion includes a collection unit in fluid communication with the coalescing unit.

Publication number: 20240011712Abstract: The present disclosure provides for heat exchanger assemblies, systems and methods. More particularly, the present disclosure provides for radially-flowing cross flow heat exchanger assemblies and systems that increase primary heat transfer surface, and related methods of use. The present disclosure provides for a cross-flow heat exchanger assembly that can be packaged cylindrically or the like (or other self-enclosed shapes), and where the heat exchanger assembly also increases and/or maximizes primary heat transfer surface area by utilizing a weave-style or interwoven heat exchanger core. A first circuit flow path can be axial or circumferential in nature, and a second circuit flow path can be radial.Type: ApplicationFiled: July 7, 2022Publication date: January 11, 2024Inventors: Raffi Mangoyan, Ousmane Gaye, Jason A. Ryon, David Saltzman

Patent number: 11802736Abstract: A heat exchanger includes a header and an annular core fluidly connected to the header. The annular core includes an inner diameter, an outer diameter, first flow channels arranged in a first set of layers, and second flow channels arranged in a second set of layers and interleaved with the first flow channels. Each of the first flow channels includes a first inlet, a first outlet, and a first axial region extending between the first inlet and the first outlet. Each of the second flow channels includes a second inlet, a second outlet, and a second axial region extending between the second inlet and the second outlet.Type: GrantFiled: July 22, 2021Date of Patent: October 31, 2023Assignee: Hamilton Sundstrand CorporationInventors: Michael Maynard, Donald E.

Publication number: 20230160640Abstract: A heat exchanger assembly includes a first member defining fluid passages therein for a first heat exchanger fluid. A second member defines fluid passages therein for a second heat exchanger fluid. The second member is engaged to the second member with an interference fit. A method of assembling a heat exchanger includes thermally resizing at least one of a first heat exchanger member and a second heat exchanger member and assembling the second heat exchanger member to the first heat exchanger member. The method includes thermally equalizing the first and second heat exchanger members to engage the second heat exchanger member to the first heat exchanger member with an interference fit.Type: ApplicationFiled: November 23, 2021Publication date: May 25, 2023Inventors: Jason Ryon, Raffi O. Mangoyan, David Saltzman, Michael Doe

Patent number: 11293703Abstract: A counter-flow heat exchanger core includes a first wall defining a longitudinal axis. The first flow path is defined within the first wall. The first flow path includes a primary flow inlet and a primary flow outlet downstream from the primary flow inlet. The heat exchanger core includes at least two hollow vanes circumferentially spaced apart and extending in a radially inward direction from the first wall. Each of the at least two hollow vanes includes a first vane wall and a second vane wall. The heat exchanger core includes a second flow path defined within the at least two hollow vanes between the first vane wall and second vane wall of each of the at least two hollow vanes. The heat exchanger core includes at least one fin extending between two of the at least two circumferentially spaced apart vanes.Type: GrantFiled: April 9, 2021Date of Patent: April 5, 2022Assignee: Hamilton Sundstrand CorporationInventors: Tomasz Meczkowski, Hubert Siudzinski, Jaroslaw Rubalewski, David Saltzman, Jakub Drzewiecki, Joseph Turney, Ryan Matthew Kelley

Publication number: 20170060369Abstract: A deivce may include a user interface configured to display at least a first graphical display and a second graphical display, a first proximity sensor having a first responsive range, and a second proximity sensor having a second responsive range. A processing system may be programmed to control the user interface by receiving an indication of a user presence within the second responsive range from the second proximity sensor while not receiving an indication of a user presence within the first responsive range from the first proximity sensor and causing the user interface to display the second graphical display. The processing system may also be programmed to receive an indication of a user presence within the first responsive range from the first proximity sensor and an indication of the user presence within the second responsive range from the second proximity sensor and cause the user interface to transition from the second graphical display to the first graphical display.Type: ApplicationFiled: May 23, 2016Publication date: March 2, 2017Applicant: Google Inc.Inventors: Vivek Goyal, John Stefanski, David Saltzman, Mark Stefanski, David Sloo, Isabel Thornton
